We give examples of integrating ABDS with HPC
We discuss how to implement this in a world of multiple infrastructures and evolving software environments for users, developers and administrators
We present Cloudmesh as supporting Software-Defined Distributed System as a Service or SDDSaaS with multiple services on multiple clouds/HPC systems.
We explain the functionality of Cloudmesh as well as the 3 administrator and 3 user modes supported
Quick Brief about " What is Hadoop"
I didn't explain in detail about hadoop, but reading this slides will give you insight of Hadoop and core product usage. This document will be more useful for PM, Newbies, Technical Architect entering into Cloud Computing.

This presentation provides a comprehensive introduction to the Hadoop Distributed System, a powerful and widely used framework for distributed storage and processing of large-scale data. Hadoop has revolutionized the way organizations manage and analyze data, making it a crucial tool in the field of big data and data analytics.
In this presentation, we explore the key components and features of Hadoop, shedding light on the fundamental building blocks that enable its exceptional data processing capabilities. We cover essential topics, including the Hadoop Distributed File System (HDFS), MapReduce, YARN (Yet Another Resource Negotiator), and Hadoop Ecosystem components like Hive, Pig, and Spark.
Big Data is a collection of large and complex data sets that cannot be processed using regular database management tools or processing applications. A lot of challenges such as capture, curation, storage, search, sharing, analysis, and visualization can be encountered while handling Big Data. On the other hand the Apache Hadoop software library is a framework that allows for the distributed processing of large data sets across clusters of computers using simple programming models. It is designed to scale up from single servers to thousands of machines, each offering local computation and storage. Big Data certification is one of the most recognized credentials of today.

Techniques to optimize the pagerank algorithm usually fall in two categories. One is to try reducing the work per iteration, and the other is to try reducing the number of iterations. These goals are often at odds with one another. Skipping computation on vertices which have already converged has the potential to save iteration time. Skipping in-identical vertices, with the same in-links, helps reduce duplicate computations and thus could help reduce iteration time. Road networks often have chains which can be short-circuited before pagerank computation to improve performance. Final ranks of chain nodes can be easily calculated. This could reduce both the iteration time, and the number of iterations. If a graph has no dangling nodes, pagerank of each strongly connected component can be computed in topological order. This could help reduce the iteration time, no. of iterations, and also enable multi-iteration concurrency in pagerank computation. The combination of all of the above methods is the STICD algorithm. [sticd] For dynamic graphs, unchanged components whose ranks are unaffected can be skipped altogether.
Levelwise PageRank with Loop-Based Dead End Handling Strategy : SHORT REPORT ...Subhajit Sahu
Abstract — Levelwise PageRank is an alternative method of PageRank computation which decomposes the input graph into a directed acyclic block-graph of strongly connected components, and processes them in topological order, one level at a time. This enables calculation for ranks in a distributed fashion without per-iteration communication, unlike the standard method where all vertices are processed in each iteration. It however comes with a precondition of the absence of dead ends in the input graph. Here, the native non-distributed performance of Levelwise PageRank was compared against Monolithic PageRank on a CPU as well as a GPU. To ensure a fair comparison, Monolithic PageRank was also performed on a graph where vertices were split by components. Results indicate that Levelwise PageRank is about as fast as Monolithic PageRank on the CPU, but quite a bit slower on the GPU. Slowdown on the GPU is likely caused by a large submission of small workloads, and expected to be non-issue when the computation is performed on massive graphs.

8. Hadoop Architecture
• Hadoop Common- A set of common libraries and utilities used by other
Hadoop modules.
• HDFS-The default storage layer for Hadoop.
• MapReduce- Executes a wide range of analytic functions by analysing
datasets in parallel before ‘reducing’ the results.The “Map” job distributes
a query to different nodes, and the “Reduce” gathers the results and
resolves them into a single value.
• YARN- Present in version 2.0 onwards,YARN is the cluster management
layer of Hadoop. Prior to 2.0, MapReduce was responsible for cluster
management as well as processing.The inclusion ofYARN means you can
run multiple applications in Hadoop (so you’re no longer limited to
MapReduce), which all share common cluster management.
9. Hadoop Architecture
• Spark- Used on top of HDFS, Spark promises speeds up to 100 times faster than the two-
step MapReduce function in certain applications. Allows data to loaded in-memory and
queried repeatedly, making it particularly apt for machine learning algorithms
• Hive- Originally developed by Facebook, Hive is a data warehouse infrastructure built on
top of Hadoop. Hive provides a simple, SQL-like language called HiveQL, whilst
maintaining full support for MapReduce. This means SQL programmers with little former
experience with Hadoop can use the system easier, and provides better integration with
certain analytics packages like Tableau. Hive also provides indexes, making querying
faster.
• HBase- Is a NoSQL columnar database which is designed to run on top of HDFS. It is
modelled after Google’s BigTable and written in Java. It was designed to provide BigTable-
like capabilities to Hadoop, such as the columnar data storage model and storage for
sparse data.
• Flume- Flume collects (typically log) data from ‘agents’ which it then aggregates and
moves into Hadoop. In essence, Flume is what takes the data from the source (say a
server or mobile device) and delivers it to Hadoop.
• Mahout- Mahout is a machine learning library. It collects key algorithms for clustering,
classification and collaborative filtering and implements them on top of distributed data
systems, like MapReduce. Mahout primarily set out to collect algorithms for
implementation on the MapReduce model, but has begun implementing on other
systems which were more efficient for data mining, such as Spark.
• Sqoop- Sqoop is a tool which aids in transitioning data from other database systems (such
as relational databases) into Hadoop.
